Roots of avian evolution: clues from relict reproductive behaviors
Remarkable, previously little known, relict reproductive behaviors of small parrots are detailed here. Because of the highly conservative nature of brain evolution, neural circuitry for many such primitive behaviors is preserved in functional condition. These behaviors can be elicited by exposing birds to appropriate conditions during breeding cycles. Founded largely on clues from these elicited responses, six...

Brackish water aquaculture: a veritable tool for the empowerment of Niger Delta communities
Poverty is generally considered as one of the major causes of food insecurity and poverty alleviation is essential in improving access to food. Among countries in the developing world, including Nigeria, the people in the fishing sectors are some of the poorest and most neglected. This is true of the fishers in the Niger Delta Region of Nigeria. Depletion in natural fish stock, lack of development in the oil rich...

Economic benefit and ecological efficiency of integrated fish farming in Nigeria
The population of people living in Nigeria has risen tremendously in recent years with its corresponding increase in demand for food. Thus, there is the need for a suitable agricultural system to meet this increasing demand and also maximize the utilization of the available limited resources without much wastage integrated fish farming offers hope in this direction. This system of farming was introduced into...

Sex steroid induced changes on the morphology of prostate of sprague-dawley rats
The effects of combined administration of ethinylestradiol (E) and testosterone (T) were studied in castrated Sprague-Dawley rats. The hormones E and T were administered three times weekly on alternate days, subcutaneously in the inguinal region for 4 weeks, 30 days after castration. E- treated animals received injections of 3 μg/kg body weight (B.W), T- treated animals received 30 mg/kg B.W., combined testosterone...

Demographic pattern and haematological profile in people living with HIV/AIDS in a university teaching hospital
The pandemic of HIV/AIDS remains a major public health concern. It continues to spread everyday, and as such, efforts should be made to achieve a screening or monitoring method that is affordable and accessible, especially in the resource poor settings. This retrospective study investigated the demographic pattern and haematological profile of people living with HIV/AIDS (PLWHA). Records of people living with HIV/AIDS...

Sesame leaves intake improve and increase epididymal spermatocytes reserve in adult male Sprague Dawley rat
Increasing concern has been expressed about the potential effects of both synthetic and natural estrogenic endocrine disruptors (EEDs) on human reproductive health in our environment in the last decade. However, little attention is paid to histomorphometric structural changes of the epididymis. We aim to evaluate the chronic exposure effects of phytoestrogens found in aqueous extract of Sesame radiatum leaves...

Appraisal of mammography in Nigerian women in a new teaching hospital
The advent of newer imaging techniques has necessitated the need for us to evaluate the distribution pattern of common and significant imaging findings on mammography at the Lagos state University Teaching Hospital. A retrospective study on all the 300 patients referred to the radiology department of LASUTH from August 2003 to August 2006 for mammography was carried out and the imaging findings were recorded using the...

Potential of locally developed forage sorghum hybrids in the Sudan
The study was conducted at two locations (Shambat and Islang) during two years (2002-2003) in Khartoum State with an objective to investigate the possibility of development of local forage hybrid sorghum [Sorghum bicolor (L.) Moench]. The material comprised four local stocks (used as pollinators) and seven introduced genetic stocks (used as females) in A3 cytoplasm and 'Pannar 888' as standard...

Antibacterial efficacy of colloidal silver alone and in combination with other antibiotics on isolates from wound Infections
A total of ten clinical bacterial isolates comprising five isolates of Escherichia coli isolated from surgical wound patients at the Federal Medical Centre, Abakaliki and five isolates ofStaphylococcus aureus isolated from the wound sites of burnt patients at the University of Nigeria Teaching Hospital, Enugu were evaluated for their susceptibility to colloidal silver at 5 and 20 ppm using agar dilution...

Spectrophotometric determination of some cephalosporin antibiotics using Prussian blue reaction
A simple, sensitive and accurate spectrophotometric method of analysis of ceftriaxone, cefotaxime and cefuroxime in pharmaceutical dosage forms has been developed and validated. The method is based on the formation of Prussian Blue (PB) complex. The reaction between the acidic hydrolysis product of the antibiotics (T = 70â—‹C) with the mixture of Fe3+ and hexacyanoferate (III) ions was evaluated for the...

Quality control assessment and the possibility of interchangeability between multisourced norfloxacin tablets marketed in Nigeria
Quality control assessment of four brands of norfloxacin tablets marketed in Nigeria was carried out in enzyme-free simulated intestinal fluid (SIF) and simulated gastric fluid (SGF) with the aim of selecting brands that are interchangeable. The possible in vivo bioavailabilities of the brands were predicated based on their respective dissolution efficiency (DE) and predicted availability equivalent (PAE). The...

A study on the performance of grain residues rations in ANAK 2000 chicks
The study was conducted to determine the performance of grain residues as feed resources in chicks. Three different rations were formulated using grain residues and salted groundnut cake. The performance of these rations (F2, F3, and F4) and commercial feed (F1) were comparatively studied for a period of ten weeks in term of body weight gain, temperature and cytological implications in ANAK 2000 chicks. The results...

Assessment of biodiversity, socio-economic status and sustainable development options at Mlawula, Swaziland
An assessment of biodiversity across an environmental gradient in an African nature reserve is made. The Forest, with its structural layers and richer soil exhibits greatest botanical diversity, followed by the Savannah and Wetland, which are impacted by human activities and flood events, respectively. The Wetland had the highest zoological (insect) diversity, followed by theForest and...
